Hi there, I'm looking for an exemplar/ most efficient 3x3 grid. This is what I wrote with blocks. Got it down to 27 lines (including end brackets on their own line. I want to see other solutions! Please share:

One thing that would be nice to be able to do in Code.org is actually restrict students from moving ahead. I had several that moved ahead quickly to this challenge on code.org and then they didn't get what the purpose of the worksheet was. They were like I already did it why do I have to do this.

Oh hey thanks for the information Baker that is really cool. Its such a tough situation because on one hand I love that I have some students that just want to keep going and learn more. But on the other hand it is kind of frustrating that they are getting so far ahead.

I am finding it tough to balance this class. Most can really fly through this stuff quick that I was thinking maybe I should make some of this self paced at some point.But I am glad to hear a new feature that might solve this problem is coming.

acutally, if i understand your request, @ben_kuehl this feature is already available! to make a lesson hidden from students, you first need to select a section, then you can choose to hide or make visible. see the example below, which starts here: https://studio.code.org/s/csp5

Oh my you are so right. That is awesome. I wish I would have remembered that because I do remember seeing that. The kids who went ahead are not going to be happy with me next class, but I have corrected what is visible and what isn't.
